MEANS FOR SECURING CARD-CLOTHING TO CYLINDERS OF CARDING-ENGINES.'

SPECIFICAI'ION formng part of Letters Patent No. 633358, dateclSeptember 19, 1899. I Application filed January 31, 1899. Serial No.703,997. (No model.)

To all whom it may concern: e

Be it known that I, JOHN DODD, engineer, a subject of the Queen of theUnited Kingdom of Great Britain and Ireland, and a residentof TheHollies, Werneth, Oldhan, in the county of Lancaster, England, haveinvented certain new and useful Improvements in Means for SecuringCard-Clothing to Cylinders of Carding-Engines for Carding Cotton, Wool,and other Fibrous Materials, of which the following is a specification.

This invention consists in improvenents in means for securingcard-Clothing to cylinders of carding-eng ines, and has for its objectthe provision of means by which the plugs to which the card-clothing ofcylinders ot' carding-engines is to be attached in order to be securedupon such cylinders may be enabled to resist distu'bance and be Securedagainst inward and outward displacement and by which it is made possibleto turn the inner surfaees of such cylinders true and smooth Withoutendangering the security of the said plugs.

In the accompanying drawings, Figure 1 is a longitudinal section of sonuch of' the cylinder of a carding-engine as is requisite for theillustration of this invention. Fig. 2 is a longitudinal section of oneof the wooden plugs employed according to this invention beforeinsertion in the cylinderof a cardingengine, and Fig, 3 is a sideelevation of one of the square wooden pegs or Wedges used in securing inposition the plugs which are employed according to this invention.

In Fig. 1, cis the cylinder to which the cardclothing b is to beSecured. c is the leather or cloth or other foundation in which theWires d forning the card-surface of the card-Clothing b, are Secured,and e is one of the fixed bends adjacent to the cylinder a.

According to this invention Icanse such of the taper plug-holes f in thecarding-engine cylinder a as are to have this invention applied to themto be tapered or countersnnk for a certain distance fron the innersurface g of the cylinder a so that such holesfshall be tapered fromboth the outer and inner faces of the cylinder a. The plugs h Whendriven into the said holes fare Secured by the usual pegs or Wedges j,driven into the plugs h. The inner taper lc'allows the plugs h to beexpanded by the driving in of the pegs or wedges j, so as to form doublecones When the pegs or Wedges j have been driven into them, and enablesthe plugs 72 to resist distnrbance and be Secured againt both inward andoutward displacement, and thus, which is the object of this invention,permits of the inner surface g of the cylinder a being turned true andsmoothwithoutendangering the securityof the plugs h and permits of thenails or tacks being driven into the plugs to secure the foundation ofthe Clothing tothe cylinder (L Without disturbing such plugs.

This invention is applicable toall the cylinders'and dofifers ofcardi-ng-engines which require to be covered with wire-clothing.

What I claim, and desire to secure by Letters Patent, is-

The combination of a carding-enginecylinder With holes countersunk ormade to taper fron both the outer surface and the inner surface of thecylinder, plugs driven into such holes and pegs or wedges driven intosuch plugs to fasten them and eXpand them into the form of double conessubstantially as set fort-h. e

In testinony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 18th day of January, 1899.

JOHN DODD.
